Answer:
Two bodies have I, though both joined in one. The more I stand still the faster I run. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
I am flora not fauna. I am foliage not trees. I am shrubbery not grass.
I have memories but none of my own whatever's on my inside is what is shown. If I'm ever different it's because you changed me I feel like a decoration here for you to arrange me.
What can you break even if you never touch it?
What can you lose that will cause other people to lose theirs too?
